Optional: Comp AI Worker Service
Comp can be used as a standalone compositor — you do not need the AI Worker for standard compositing. The Worker is a separate command-line component used only by the optional AI modules: SAM3 (prompted image segmentation) and MatAnyone2 (mask-edge refinement). Current Worker release: v0.1.2.

Starting the Worker
Replace the placeholder paths and TARGET. Use cuda for an NVIDIA GPU, mps for Apple GPU acceleration, or cpu. Binding to 127.0.0.1 keeps the Worker local to the same machine.
macOS / Linux shell
"/path/to/comp-worker" serve \ --family-bundle "mat2=<worker-root>/family_bundles/mat2" \ --family-bundle "sam3=<worker-root>/family_bundles/sam3" \ --target TARGET \ --bind-host 127.0.0.1 \ --port 19282 \ --temp-dir "<path-to-temp-directory>/comp-worker" \ --cpu-threads 0 \ --precision fp32 \ --verbose
Windows PowerShell
& "C:\path\to\comp-worker.exe" serve ` --family-bundle "mat2=C:\path\to\worker\family_bundles\mat2" ` --family-bundle "sam3=C:\path\to\worker\family_bundles\sam3" ` --target TARGET ` --bind-host 127.0.0.1 ` --port 19282 ` --temp-dir "C:\path\to\temp\comp-worker" ` --cpu-threads 0 ` --precision fp32 ` --verbose
For a reduced-memory test, add --max-propagation-history-depth 2 and --max-mem-frames 2.
